The triode section was designed for a variety of uses including sync separation. The pentode was designed for use as a video output stage. Introduced in 1958 when the UK had a 405 line VHF television service and a video bandwidth of 3 MHz maximum.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 58 mm tall.
